TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 793,470, dated June 27,1905.

Application filed December 31, 1904. Serial No. 239,110.

To all whom it may concern:

Be it known that -I, BERNHARDT SCHIBLER, J r., a citizen of the UnitedStates, residing in Paterson, Passaic county, New Jersey, have inventedcertain new and useful Improvements in Tobacco-Pipes; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

My invention has for its object to provide a tobacco-pipe with a simple,inconspicuous, and effective means for clearing it of the mass of ashesand half-smoked tobacco which is left therein after use and which ifattempted to be removed by striking the pipe against some rigid surfaceoften leads to damage to the pipe, especially if made of meerschaum.

My invention will be found fully illustrated in the accompanyingdrawings, wherein Figure 1 illustrates a pipe with its bowl portion insection, so as to show the device of my invention. Fig. 2 is a plan viewof the bowl portion of the pipe with said device in place therein. Fig.3 illustrates a detail, and Fig. 4 shows a modified form of theinvention.

In the'bowla of the pipe 6 I place a spiral 0, formed, say, of wire andpreferably of such diameter as to snugly fit the bowl. The lower endportion cl of the spiral is straight and is in the spirals axis, beingjournaled in a hole e in the bottom of the bowl, through which itprotrudes. Said end portion has a shoulder f, which abuts against theinside surface of the bowl, and at its protruding extremity, which issquared, as at y, it carries a knurl or milled finger-piece h, which mayhave a split hub 6, receiving the squared extremity of the portion cl ofthe spiral.

This means of attaching the knurl permits the spirals to be made andsold separately from the pipes, and to accommodate various sizes ofpipes the spiral may have a radius a little larger than the radius ofthe average pipe-bowl, its inherent compressibility being relied on tomake it fit bowls of the smaller sizes.

In Fig. 4: the spiral is shown as made of a spirally-wound strip ofmetal having its forward edge 1' sharp and set snugly against the insidesurface of the pipe-bowl. This spiral is calculated to better clear awaycharred tobacco, which cakes up the surface of the bowl. In this figureis also shown a bushing 16, having its ends expanded to secure it in thebowl, as at Z, said bushing serving as a bearing for the spiral.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is

1. The combination, with a tobacco-pipe, of a spiral for clearing outthe bowl thereof arranged to rotate in said bowl with its axis 00-incident with that of the bowl, said spiral having an axial projectionprotruding through the bowl-bottom and forming a handle for rotatingsaid spiral, substantially as described.

2. The combination, with a tobacco-pipe, of a spiral for clearing outthe bowl thereof arranged to rotate in said bowl with its axiscoincident with that of the bowl, said spiral having an axial projectionprotruding through the bowl-bottom, and a finger-piece attached to theprotruding end of said projection, sub stantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this16th day of November, 1904.
